If you're planning to swim at Sioux Falls' new indoor pool in August, you might want to double-check that the $24 million facility will be open on the day you want to go.

Starting next week, the pools at the Midco Aquatic Center will close on a staggered schedule for routine annual pool maintenance, with the entire facility shut down Aug. 7-13.

“Due to the year-round operation of the Midco Aquatic Center, it is important to be able to schedule annual maintenance to keep the facility in top condition,” Don Kearney, director of Sioux Falls Parks and Recreation, said in a news release.

The maintenance work requires the pools to be drained to complete an inspection, some additional deep cleaning, and other items not possible when people are using the facility.

Kearney said in an interview that the city chose the beginning of August to perform its annual maintenance because outdoor pools will still be in season, and other activities happening in the community at that time are expected to reduce the public's demand for indoor swimming.

"We planned our programming around the August shutdown, and typically people are interested in the fair and other back to school types of activities in August," Kearney said.

From July 31 to Aug. 6, the recreation pool, warm water pool and outdoor spray pad will be closed, but the 50-meter pool will remain open.

From Aug. 7 to Aug. 13, the entire facility will be closed.

From Aug. 14 to Aug. 20, the 50-meter pool will be closed, but the recreation pool, warm water pool and spray pad will be open again.

The entire facility is scheduled to reopen for regular business hours on Aug. 21.

It's unclear how much revenue having the Midco pools closed for an entire week will cost the city, but Kearney said some will be offset by not having to staff the indoor pools during the closures.

“We would like to thank the public for their patience and also invite them to visit one of our outdoor facilities during this annual maintenance period,” Kearney said.
